The new high-efficiency pressure regulating device for circulating water pumps is an energy-saving product with independent intellectual property rights, This device has the advantages of small size, environmental protection, long service life, maintenance free, and can significantly reduce the power consumption of the system driven pump, greatly reducing the operating cost of the equipment.

It mainly consists of an inner pipe, a guide plate, a water spray port, and a pressure regulating plate.


working principle:

In the circulation system, the head of the circulation pump is to overcome the resistance of the system pipeline network. Traditional centrifugal pumps have the highest pressure and flow rate at the outlet of the circulation pump in the entire circulation system at the moment of start-up. The JF type new circulating water pump pressure regulating device mainly utilizes the instantaneous high pressure and high flow rate at the outlet of the circulating pump. Through the unique internal design of the water pump pressure regulating device, negative pressure is formed inside the device, which generates a suction force on the outlet of the water pump. According to the theory of fluid mechanics, when the suction pressure of water decreases, its gasification temperature also decreases. When the water pump is working, the pressure at the inlet of the impeller is the lowest. At this point, the water will vaporize and produce bubbles. At the same time, due to the decrease in pressure, oxygen dissolved in the water will also escape and produce bubbles. Through the pressure regulating device of the water pump, the gas water mixture produced by bubbles can be reduced or eliminated, improving the operating efficiency of the water pump. The improved efficiency can replace part of the head of the circulating pump and overcome system resistance. With the flow rate of the circulating pump unchanged, once the head of the circulating pump decreases, the power of the circulating pump will significantly decrease, thus achieving the goal of saving equipment operating costs.
